Application of the Riccati hereditary mathematical model to the study of the dynamics of radon accumulation in the storage chamber [PDF]

EPJ Web of Conferences, 2021
The article proposes a mathematical model of radon accumulation in a chamber, which takes into account the hereditary properties of the environment in which radon migrates.

Fermilab accumulator magnets vacuum chamber heating system [PDF]

Journal of Vacuum Science & Technology A: Vacuum, Surfaces, and Films, 1985
The Fermi National Accelerator Laboratory (Fermilab) is building an accumulator ring to store antiprotons for high energy physics proton–antiproton collisions in the Tevatron accelerator. The accumulator ring, approximately 474 m in circumference, consists of many quadrupole and dipole magnets connected with stainless steel vacuum chambers for beam ...

Non-steady-state closed dynamic chamber to measure soil CO2 respiration: A protocol to reduce uncertainty

Frontiers in Environmental Science, 2023
Non-steady-state closed dynamic accumulation chambers are widely used to measure the respiration of terrestrial ecosystems, thanks to their low cost, low energy consumption and simple transportability, that allow measurements even in hostile and remote ...

Radon release rate from soil into the surface atmosphere specifics

Vestnik KRAUNC: Fiziko-Matematičeskie Nauki, 2021
The paper presents the results of the analysis of long-term series of monitoring data on the radon flux density. They were produced using a accumulation chamber of our own design, which allows, in terms of the readings of alpha radiation counters, to ...

Quantitation of nanoparticle accumulation in flow using optimized microfluidic chambers [PDF]

Journal of Drug Targeting, 2013
The vascular cell adhesion molecule-1 (VCAM-1) targeting peptide sequence, VHPKQHR, is a promising moiety for targeting atherosclerosis through incorporation into nanoparticles such as dendrimers and liposomes.We aim to develop VCAM-1-targeted nanoparticles that effectively accumulate on the endothelium under shear conditions and to develop robust ...

P62 accumulates through neuroanatomical circuits in response to tauopathy propagation

Acta Neuropathologica Communications, 2021
In Alzheimer’s disease and related tauopathies, trans-synaptic transfer and accumulation of pathological tau from donor to recipient neurons is thought to contribute to disease progression, but the underlying mechanisms are poorly understood.

Distribution of Gold Nanoparticles in the Anterior Chamber of the Eye after Intracameral Injection for Glaucoma Therapy

Pharmaceutics, 2021
In glaucoma therapy, nanoparticles (NPs) are a favorable tool for delivering drugs to the outflow tissues of the anterior chamber of the eye where disease development and progression take place.

Repeatability of gaseous measurements across consecutive days in sheep using Portable accumulation chambers [PDF]

Journal of Animal Science, 2021
Abstract Portable accumulation chambers (PAC) enable gaseous emissions from small ruminants to be measured over a 50 min period, to date however, the repeatability of consecutive days of measurement in the PAC has not been investigated. The objectives of this study were to investigate: 1) the repeatability of consecutive days of gaseous ...
